1. 概述

本文首先會簡單介紹Kylin的安裝配置，然後介紹啟用Kerberos的CDH叢集中如何部署及使用Kylin。

Apache Kylin™是一個開源的分散式分析引擎，提供Hadoop/Spark之上的SQL查詢介面及多維分析（OLAP）能力以支援超大規模資料，最初由eBay Inc. 開發並貢獻至開源社群。它能在亞秒內查詢巨大的Hive表。

1.2 環境說明

  • CDH版本：5.11.2
  • Linux版本：7.4.1708
  • Docker版本：Docker version 18.06.0-ce
  • JDK版本：1.8
  • 操作使用者：root

2.Kylin安裝配置

2.1 安裝

此處以Kylin 2.0.0版本為例。
社群版Kylin地址：https://archive.apache.org/dist/kylin/

[root@node-3 ~]# cd /usr/local/src/
[root@node-3 src]# wget https://archive.apache.org/dist/kylin/apache-kylin-2.0.0/apache-kylin-2.0.0-bin-cdh57.tar.gz
[root@node-3 src]# tar xf apache-kylin-2.0.0-bin-cdh57.tar.gz 
[root@node-3 src]# cp -a apache-kylin-2.0.0-bin /usr/local/
[root@node-3 src]# ln -s /usr/local/apache-kylin-2.0.0-bin /usr/local/kylin

2.2 環境配置

export BASE_PATH_BIG=/opt/cloudera/parcels/CDH/lib

#added by Hbase
export HBASE_HOME=$BASE_PATH_BIG/hbase

#added by HCat
export HCAT_HOME=/opt/cloudera/parcels/CDH/lib/hive-hcatalog/share/hcatalog

#added by Kylin
export KYLIN_HOME=/usr/local/kylin
export PATH=$HBASE_HOME/bin:$PATH

然後執行source /etc/profile生效。

2.3 Kylin配置

編輯/usr/local/kylin/conf/kylin.properites檔案，新增以下配置：

Kylin2.0+版本配置的名稱有變化，具體參考：https://github.com/apache/kylin/blob/2.0.x/core-common/src/main/resources/kylin-backward-compatibility.properties

## 修改配置（替換地址）
kylin.rest.servers=192.168.100.102:7070

## 新增配置
kylin.job.jar=/usr/local/apache-kylin-2.0.0-bin/lib/kylin-job-2.0.0.jar
kylin.coprocessor.local.jar=/usr/local/apache-kylin-2.0.0-bin/lib/kylin-coprocessor-2.0.0.jar
## 替換地址
kylin.job.yarn.app.rest.check.status.url=http://cdh-node-2:8088/ws/v1/cluster/apps/${job_id}?anonymous=true
kylin.job.mr.lib.dir=/opt/cloudera/parcels/CDH-5.11.2-1.cdh5.11.2.p0.4/lib/sentry/lib
配置說明：

更多配置請參考官網配置指南。

2.4 建立使用者

在每個節點建立Kylin使用者

useradd kylin

3. Kerberos配置

3.1 建立kylin賬號

在Kerberos server上建立kylin賬號：

[root@cdh-node-1 /]# kadmin.local
Authenticating as principal admin/admin@HWINFO.COM with password.
kadmin.local:  addprinc kylin
WARNING: no policy specified for kylin@HWINFO.COM; defaulting to no policy
Enter password for principal "kylin@HWINFO.COM":
Re-enter password for principal "kylin@HWINFO.COM":
add_principal: Principal or policy already exists while creating "kylin@HWINFO.COM".
kadmin.local:

3.2 生成keytab檔案

生成kylin賬號keytab檔案：

xst -norandkey -k klin.keytab kylin@HWINFO.COM

將kylin.keytab複製到每個kylin節點上。

3.3 定時重新整理kt

在kylin節點上配置定時任務進行kinit命令：

kinit -k -t /root/kylin.keytab kylin@HWINFO.COM

新增定時任務,這裡設定每天凌晨1點執行一次，可根據kerberos的過期時間自己配置。

  • 編寫shell指令碼：
[root@cdh-node-2 security]# cat init_kt.sh
#!/bin/bash
kinit -kt ./kylin.keytab kylin@HWINFO.COM
  • 新增定時任務：
[root@cdh-node-2 security]# crontab -e

# 新增以下內容
0 1 * * * root /home/security/init_kt.sh  > /tmp/kylin-ktinit.log 2>&1

# 檢視定時任務
[root@cdh-node-2 security]# crontab -l
0 1 * * * root /home/security/init_kt.sh  > /tmp/kylin-ktinit.log 2>&1

3.4 新增Hive許可權

  • 登入Hive
    使用擁有操作hive許可權的kerberos賬戶登入beeline：
[root@cdh-node-3 hive]# beeline -u `jdbc:hive2://cdh-node-3:10000/default;principal=hive/cdh-node-3@HWINFO.COM`
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=512M; support was removed in 8.0
Java HotSpot(TM) 64-Bit Server VM warning: Using incremental CMS is deprecated and will likely be removed in a future release
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=512M; support was removed in 8.0
scan complete in 2ms
Connecting to jdbc:hive2://cdh-node-3:10000/default;principal=hive/cdh-node-3@HWINFO.COM
Connected to: Apache Hive (version 1.1.0-cdh5.11.2)
Driver: Hive JDBC (version 1.1.0-cdh5.11.2)
Transaction isolation: TRANSACTION_REPEATABLE_READ
Beeline version 1.1.0-cdh5.11.2 by Apache Hive
0: jdbc:hive2://cdh-node-3:10000/default>
  • 新增kylin許可權
    將admin角色許可權賦予kylin：
0: jdbc:hive2://cdh-node-3:10000/default> grant role admin to user kylin;
INFO  : Compiling command(queryId=hive_20180914174141_6359e1a1-251f-4116-b646-0aa9f55dcfa8): grant role admin to user leili
INFO  : Semantic Analysis Completed
INFO  : Returning Hive schema: Schema(fieldSchemas:null, properties:null)
INFO  : Completed compiling command(queryId=hive_20180914174141_6359e1a1-251f-4116-b646-0aa9f55dcfa8); Time taken: 0.069 seconds
INFO  : Executing command(queryId=hive_20180914174141_6359e1a1-251f-4116-b646-0aa9f55dcfa8): grant role admin to user leili
INFO  : Starting task [Stage-0:DDL] in serial mode

INFO  : OK
No rows affected (0.528 seconds)

3.5 新增Hbase許可權

使用擁有操作hbase許可權的kerberos賬戶登入hbase shell：

[root@cdh-node-3 hive]# hbase shell
Java HotSpot(TM) 64-Bit Server VM warning: Using incremental CMS is deprecated and will likely be removed in a future release
18/09/14 17:44:40 INFO Configuration.deprecation: hadoop.native.lib is deprecated. Instead, use io.native.lib.available
HBase Shell; enter `help<RETURN>` for list of supported commands.
Type "exit<RETURN>" to leave the HBase Shell
Version 1.2.0-cdh5.11.2, rUnknown, Fri Aug 18 14:09:37 PDT 2017
  • 給kylin使用者授權
base(main):001:0> grant `kylin`,`RWXCA`
0 row(s) in 0.5830 seconds

切換到kylin使用者重新登入hbase shell，測試一下：

hbase(main):001:0> whoami
kylin@HWINFO.COM (auth:KERBEROS)
    groups: kylin

hbase(main):002:0> create `test`, `cf`
0 row(s) in 2.6930 seconds

=> Hbase::Table - test
hbase(main):003:0> list
TABLE
test
1 row(s) in 0.0310 seconds

3.6 執行Kylin檢查

[root@cdh-node-2 bin]# ./check-env.sh
Retrieving hadoop conf dir...
KYLIN_HOME is set to /usr/local/apache-kylin-2.0.0-bin

3.7 啟動kylin服務

先確認主機使用kerberos憑據為kylin，再啟動：

[root@cdh-node-2 bin]# klist
Ticket cache: FILE:/tmp/krb5cc_0
Default principal: kylin@HWINFO.COM

Valid starting       Expires              Service principal
09/14/2018 17:48:28  09/15/2018 17:48:28  krbtgt/HWINFO.COM@HWINFO.COM
    renew until 09/21/2018 17:48:28
[root@cdh-node-2 bin]# ./kylin.sh start
Retrieving hadoop conf dir...
KYLIN_HOME is set to /usr/local/kylin
Retrieving hive dependency...
Retrieving hbase dependency...
Retrieving hadoop conf dir...
Retrieving kafka dependency...
Retrieving Spark dependency...
KYLIN_JVM_SETTINGS is -Xms1024M -Xmx4096M -Xss1024K -XX:MaxPermSize=128M -verbose:gc -XX:+PrintGCDetails -XX:+PrintGCDateStamps -Xloggc:/usr/local/kylin/logs/kylin.gc.3982 -XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=10 -XX:GCLogFileSize=64M

A new Kylin instance is started by root. To stop it, run `kylin.sh stop`
Check the log at /usr/local/kylin/logs/kylin.log
Web UI is at http://<hostname>:7070/kylin

4. 使用Kylin Sample測試

Kylin本身自帶了一個測試例子，建立流程如下：
執行sample.sh指令碼，這個主要是建立kylin的project、model、cube以及相關的hive表等。

[root@cdh-node-2 bin]# ./sample.sh
Retrieving hadoop conf dir...
Retrieving hadoop conf dir...
KYLIN_HOME is set to /usr/local/kylin
Loading sample data into HDFS tmp path: /tmp/kylin/sample_cube/d

...

Sample cube is created successfully in project `learn_kylin`.
Restart Kylin server or reload the metadata from web UI to see the change.

進入Kylin Web介面system – reload metadata
然後構建示例的cube，如果構建成功，並且能成功執行查詢命令，則表示整個配置全部完成。

構建成功
